I recently upgraded my system to Win98 and loaded the HP driver upgrades, but I can't get my scanner to work. When I check the device in device manager, it is identified as HP C5190A and says it is working properly. However, when I click on the "Scanners & Cameras" icon in Control Panel and then access the properties for HP ScanJet 5100C, it says the status is unavailable. If I launch the Precision Scan software from HP or try to test the scanner from the properties box, my system crashes. Any suggestions?
